Непривилегированный ping6 не работает

Я пытаюсь запустить мой сервер CentOS v7 для запуска IPv6. Корневые работы, он может пинговать с помощью «ping6 ipv6.google.com», а ifconfig выглядит великолепно; Я вижу строки:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 149.202.217.90 netmask 255.255.255.0 broadcast 149.202.217.255 inet6 fe80::ec4:7aff:fec4:d912 prefixlen 64 scopeid 0x20<link> inet6 2001:41d0:1000:1c5a:: prefixlen 64 scopeid 0x0<global> 

Но как непривилегированный пользователь, я не могу ping ipv6, и я не вижу адреса inet6 в ifconfig.

Что происходит? Почему мои пользователи не видят одни и те же интерфейсы, настроенные так же, как и root?

[редактировать]

Как запрошено, ip as и ping6 -c1 ipv6.google.com вывод:

Я добавил вывод ifconfig ниже:
